I [IMPROVEMENT nv'e,RAIN-DRlLLs.'`

Specification forming part of Letters Patent No. 176,967, dated May 2,' 1876 application filed December 30, 1875. y

To Vall ,whom it may. concern' Beit known Athat I, EDWARD' KUHNs, of

Logansport,in the 'county of Cass and State" of Indiana, have invented certain new and useful Improvements in Grain-Drill'sgand 'I d 5 hereby declare that the followingl is a full,

clear, and exactdescription thereof, which will enable others skilled in the art to which it pertains 'to make anduse the same, reference being had to the accompanying drawings, and to the letters of reference markedl thereon, which form a part of this specification-'- Figure l being a plan view of the feed-wheel and its shaft audthe sliding grain-regulator; Fig. 2, a sectional elevation on line y y of Fig. 4; Fig. 3, a section on line w xof Fig. 1; and Fig. 4, a side elevation, showing the seed-cup, the feed-wheel, and its-shaft, and also the grainregulator, the parts beingin position with reference to each other.

This invention relates to mechanism for distributing grain from the hoppers of grainculty has arisen, owing to the fact that the grain has been allowed to fall in between the end of the wheel and the portion of the cup y toward which it, is moved, or between the grain-regulator and'said cup, as a consequence of which it has been nearly impossible to move the wheel or regulator, and quite so without mashing more or less of the grain, and thus destroying it. y

' This invention has for its object the remedying of the difficulties alluded to, whichv is believed to be accomplished by the construction and combination of parts shown and described.

In constructing devices of this character, I use a feed-cup, A, of any suitable size and form that will receive and support the feedwheel and A the grain-regulator. One of the vertical sides of this cup has an annular apertureformed in it for the reception of the rotating coliar B, which is made to rotate freely iii said aperture., This collar has formed in it tions forinedvto enter thecavities between the ribs of said wheel, so that it may be rotated p'ass through it, and be` moved vtherein withoht allowing any grain to pass out at'that ,in connection with this cup, is corrugated upon its outer surface, the corrugations to be formed spirally or in a line with its axis, as preferred, and is to be of such a length that when placed in position to deliver the greatpasses through the annular collar B shall extend to or beyond its outer surface, and thus prevent the escape of grain, and be at all times in a position to rotate the collar. This feedwheel is mounted upon a shaft, D, which may extend the` entire length of the machine, and carry all of the feed-wheels; or vit may be tween the cups. To this shaft the feed-wheels are secured, so as to be rotated thereby, and to be moved horizontally therewith or therein order that the grain-regulator may be connected thereto and move with it. f

The grain regulator, already alluded to, is lettered F, and is peculiar in construction, it consisting of a plate of segmental form, hav- F1,' which effectually prevents the regulator from rotating. To the inner end of the radial ange Fl there is attached a projection, F3, which, when the regulator is moved, prevents the grain from falling over into the segmental portion, and also serves to contract or enlarge the delivery aperture for the grain. The inner end of the segmental portion of the regulator is provided with an in wardly-projectin g ilange, G, which enters into the annular groove E, formed in the feed-wheel C, and aids in uniting the two parts, and it also prevents the an openin g `of sufficient diameter to admit thcq` passage through it of the feed-wheel, and has 'upon its 1nteriors urface a series of projecthereby. Theopposite vertical lplate of the seed-cup has formed in it an aperture, which .Y is so constructed as to permit the shaft whichL Y carries the feed-wheels and grain-regulator to point. The feed-wheel G, which is to be used est amount of grain the end thereof which' made in sections and coupled together beon, its inner endbeing provided with a groove ing attached to it a radially-extending flange, c*

grain from passing into thespacc between the cup and regulator. 4In order that the grain may be prevented from passing over the feed- Wheel, a shield, H, is placed in the cup A, as shown in Fig. 2, it being so arranged as to come nearly in contact with the same, and

.with the upper edge of the segmental portion of the regulator.

From the description given, and from the drawings, it will be seen that, when it is desirable, the entirelength of the wheel can be used for distributing grain; or it maybe used in any position between that and the closed position, and thus be made to sow any desired amount of grain upon a given area of ground, and that this may be done Without any compression of 'the grain or breaking thereof.

Having thus described my invention, what I claim, and desire to secure-by Letters Patent isp Y l. A seed-cup for grain-drills, one of the vertical plates of which is provided with an annular aperture for the reception of arotating collar',v and the other with an aperture for the segmental passage of the sliding grainregulator, substantially as an'd for the purpose specied.

2. The sliding grain-regulator F, having a segmental portion, as described, for the purpose of preventing the grain from falling into the same when the delivery-orice is dimin-` ished, and a projection, F3, for contracting the delivery-orice, substantially as set forth.

3. The combination, in a grain-drill, of the feed-Wheel, shaft D, and a segmental sliding feed-regulator passing through one of the vertical walls of the seed-cup, substantially as and for the purpose set forth.

4. The combination, in a grain-drill, of a cup, A, having in one of its ends a circular aperture for the reception of a rotating collar, and in the other a segmental aperture for the passage of the grain-regulator, a feed-wheel, C, a shaft, D, and a segmental sliding grainregulator,A the parts being arranged to operate substantially as and-for the purpose set forth.

5.-'lhe combination, in `a ygrain-drill, of a grooved feed-wheel, a rotating collar adapted to be rotated by said Wheel by having projec`
